To ALL WHoM IT MAY coNcnRN:4

Bc it-known that I, JOHN HENRY BUTLR, of the town of Scottsville, in thecounty of Allen, `and State of Kentucky, have invented a new and usefulmachine for raking and pulverizing ground, and preparing it forcultivation, and or cultivating it after seed hasibcen planted. Myinvention may be denominated A Circular' and Rotary Rake; and I. dohereby declare that the'fqllowing is a, full, clear, Aand exactdescription-of the con.. struction and operation of the saine, referencebeing had to the accompanyingdrawings, and the letters-of referencemarked thereon. v V I i My invention, or circular and rotary rake,consists of a circle, made of Wood, iron, 4or otherhstrong and suitablematerial, of any diinensions the constructor pleases, marked a in thedrawings. The periphery-of the circle must be sufficiently broad, andthick, and strong to hold iron or iv'ood'en teetbinposition, so thatthey will not give way, 4as represented-,in the accompanying drawings,(see` No.v 1.) Across th/ecentre of the'circle there must be one or tivopiece'sof the same material as the c ircular frame,suilicientlystrongtohoid teeth, as above described'.-v Thesecross-pieces must be attached to the circular frame at theirenils,.ivitl1 suchstrength .ns not t6 give way by theworlzing of themachine, as represented vin the drawings.` Upon-the top andA 'in theVcentre of these cross-pieces, and in the centreof the circle, theremust be a thin .plate of iron, steel, or other hard and suitable metal,capable, as far 'as can be, ofressting the eii'ects offrietion,/cxtending from side to side ofthe cross-pieces.'

The teeth for'pulverizing the ground are to be inserted into thecircular franie, and into-thecross-picees, as represented in thedrawings, and Vmay he made as numerous,-according to thesize ofthe rake,asl'is desired. vThrough' the centre'of the circle, and at theintersection of thecross-heams or piecesfis to be inserted a piece of"iron, steel, or otherl suitable substance, and is tubo made very'tightand strong. rWherc it passes above the plate, it must beinadefperfectly' rounihso that it muy revol'vcin the handle hywhich themachineor rake is worked. This piece of iron Vor steel, or vot'heusuit-able sub`stan::e, is to rise perpendicular. to` the plane of'.

the circular fra-me, and is vto pass' through a hole inode in tle lowerend of the handle to receive it, a`ndi by means oifa sereni4 andscrew-tap, to connect the handleand other part of the rake ormachi'ne,(as represented:

in Nos. y'1 ,and 3 in the Vdrawings but, .at thesaniel-time, is toalloivafree rotary motion of` thecireular frame.. l in the handle.lhere' must be .a plate attachedjzo the lower part oi' the handle, asrepresented in Nof of the drawings, by which it is attached to -thecircular frame. It must be of' sufficient thickness Ato given-,steadymotion vtothe revolution of the lower part ,of'therakeV '.lhere` must bea washer between the screw-tap and the plate connecting 2the -handle andcircular frame. The handle-Amay be'ofany length desired,` and be 'madeto.

ascend from the circular frame at anl :ingle lof forty-ve degrees, moreor'less, as desired. The great object in making the connection betweenthe handle and'circulnr frame is, strength andiV diminution of friction,so as still toallov a f ree revolutionof the circular frnmeether tray. iWith a view to prevent lthe revolution of the circle, and make the rakeoperate/on the` ground as a common rake, I have inserted an iron stapleon each side of the handle, into w.l 1i`chhooks,vattached toene-oftbe'cross-pieces, one on each side 'of the centre, maybe fastened, so asto holdthehandle rm in one'positicn, (see No. ,34 of the drawings.)- Theiron hooks, when not in usefor the purpose desig'ied,`lare'preventedfioni danglingin the way, and impeding the use of theinachine, as represented in No. 3 of the drawings.' i

What I claim as, my invention, and desire to secureby Letters Batent,is--'A The'circular and rotary construction of the machine abovedescribed, lconnected. tvithh handle, n s above described, and havingteeth inserted in, the usual manner in the circular-frame, and by means-ofriron hooks and staples, above described, preventingtbe-rotarymotioncf themachine, at; pleasure,'and thereby converting it'into a commen rake'. v r
